Fort Bend County investigators have identified a woman who drowned in a backyard pool in Katy on Saturday.

Willowfork Fire Department responders pulled Beverly Lamkin, 57, out of the pool about 5:20 p.m., and efforts by EMS personnel to revive her were unsuccessful, according to a press release from the Fort Bend County Sheriff's Office.

Deputies learned from Lamkin's son that she was watching the homeowner's pets while they were out. She also was taking care of her 4-year-old grandson, who made the call to his father that Lamkin was floating in the pool, according to the release.

The son told deputies his mother was diabetic and he had seen her pass out before.

The home is located in the 2000 block of Fairbranch Court in the Greenway Village subdivision.
